Address Registers

Six registers make up the 48-bit Address:
• Address[47:40] — Address 1

• Address[23:16] — Address 4
• Address[15:8] — Address 5
• Address[7:0] — Address 6
Example: Address is 00-A0-24-D1-7F-02
• Address 1 = 0x00
• Address 2 = 0xA0
• Address 3 = 0x24
• Address 4 = 0xD1
• Address 5 = 0x7F
• Address 6 = 0x02
The detailed bit descriptions follow the six registers' bit maps.
